In-Advance Lane Changing and Traffic Volume Distribution Over Lanes at Expressway On-Ramp Sections

The distribution of the volume of incoming through traffic over lanes at the upstream-side end of on-ramp merging section is a key factor in designing the geometry of on-ramp junctions. This distribution may be affected by the merging traffic volume and the geometric design of the junction. However, the mechanism how the geometric and traffic conditions affect the incoming traffic distribution over lanes is not sufficiently clarified. This study analyses the behavior so-called “in-advance lane changing”, and develops a model that illustrates how “the distribution of traffic over lanes at the upstream-side end of the on ramp merging” is formed under the influence of “traffic phenomena that take place at the on-ramp merging sections.” The proposed model shows rather good capability for reproducing observed traffic phenomena.
